A Brake-Testbench for Research and Education

This paper outlines the concept of a laboratory brake-testbench for education and research. It was developed to investigate the deceleration behaviour of a car's wheel during braking. The major components of the testbench are a driven wheel which is equipped with a disc brake and a rotating steel cylinder. The testbench is mainly used to test alternative antilock braking algorithms and to teach students of automotive engineering the principles of conventional braking systems. Furthermore it is used as a test object for robust nonlinear observers especially in automotive applications.
